My 4yr old Harman Kardon AV receiver suddenly failed. I am currently temporarily residing in USA but my AV receiver is back home in Singapore. So the info is second hand from my wife back home.
The AV receiver suddenly failed giving a loud noise from all speakers (on all source selection upon powering on - even with volume pot all the way down). I listened to the noise (transmitted via skype) and it sounded like a loud DC output, kinda like "teeehhhhhhhhhh" extremely loud and unchanging in tone or volume upon power on.
I've detached the speakers to protect them.
So does this sound like DC output to speakers? What is the most likely failure source - capacitors?
I'll returning home soon but am wondering if diagnostics and repair is easy or economically viable - if not I may have to dispose of it.
thanks
